Violence plagues Ariz. Indians

"Using tribal enrollment figures, the report showed a murder rate of 29 per 100,000 population, compared with a national rate of 5.6 per 100,000.

With six killings among 6,405 tribal members, the Salt River Pima-Maricopa Community homicide rate is 17 times the national average. The Gila River Indian Community, with 11,257 enrollees, counted 11 murders. By comparison, major Valley cities averaged slightly more than seven killings per 100,000 last year.

The Navajo Nation, America's most-populated reservation, reported 63 murders among 275,000 enrolled members for a rate of 23 per 100,000. The Hopi Tribe, with 10,474 enrolled, had no homicides.

Humetewa and others attribute the Indian crime rate to socio-economic factors like unemployment, broken families, lost cultural values and the emergence of gangs."

As resident of Arizona I find this report disturbing.

Homicide rates are generally higher among poor people; the stereotypical reservation has pretty much all the risk factors you could ask for.
